Summit Fever (Ultra HD Blu-ray & Blu-ray)

As the successor to the Blu-ray Disc, the Ultra HD Blu-ray is an optical data storage device for movies in ultra-high definition format. The eponymous Ultra HD resolution is a maximum of 3840 × 2160 pixels. In contrast to its predecessor, it also supports a higher contrast range, a higher refresh rate and a larger color space. Normal Blu-ray players cannot play the new media. Ultra HD Blu-ray-capable devices are usually backward compatible.

The Blu-Ray was developed as a high-definition successor to the DVD and offers a significantly increased data rate and storage capacity compared to its predecessor. Blu-Rays can therefore store movies with significantly better resolution and offer enormously high picture quality on corresponding screens. Blu-Ray players are usually backward compatible with DVDs, so that they can also be played.
